We describe the history, guiding mechanism, recent advances, applications, and future
prospects for hollow-core negative curvature fibers. We first review one-dimensional slab …

Abstract Lab-in-a-Fiber (LIF), a counterpart of Lab-on-a-chip, however, deployed within the
cylindrical optical fiber geometry, emerges as a promising approach into the development of …

In this paper, we numerically investigate various hollow-core anti-resonant (HC-AR) fibers
towards low propagation and bend loss with effectively single-mode operation in the …

Understanding the impact of the cladding tube structure on the overall guiding performance
is crucial for designing a single-mode, wide-band, and ultra low-loss nested hollow-core anti …

A novel single-polarization single-mode double-ring hollow-core anti-resonant fiber with two
single-polarization regions (1545–1553 nm and 1591–1596 nm) is proposed. Single …

We present a numerical investigation on the effect of introducing the second ring of
antiresonant tubes on the guiding properties of the negative-curvature fiber. We determine …

A double cladding nested antiresonant hollow core fiber is reported in this article. We
demonstrated that the addition of nested elements in the second cladding ring and the …

In this paper, we propose an ultra-broadband polarization beam splitter for a dual hollow-
core anti-resonant fiber. We divide the fiber core into two parts by introducing the two longer …

In this paper, a highly birefringent polarization maintaining low losses and a single mode
antiresonant hollow core fiber is proposed and analyzed, that is able to exhibit better …

We design, fabricate, and demonstrate the first hollow-core air-gap anti-resonant fiber
coupler in a dual hollow-core anti-resonant fiber (DHAF) structure. The coupling takes place …
